从Windows 7服务(会话0)读取HID设备时出现问题 [英] Problems reading HID device from Windows 7 service (Session 0)

问题描述

我在Windows 7中从Session 0服务下的HID设备读取时遇到问题.在普通桌面用户下，我可以从设备上正常读取.但是，当我尝试在Session 0下使用Overlapped I/O读取它时，WaitForSingleObject()总是返回 WAIT_TIMEOUT，并且ReadFile()的缓冲区从不包含任何有效数据.在我看来，这似乎是一个Session 0隔离问题，但是我找不到有关如何解决此问题的任何信息.在会话0下从HID设备读取是否无法正常工作?

Hi, I have an problem reading from a HID device under a Session 0 service in Windows 7. Under a normal desktop user, I can read from the device fine. However, when I try to read from it using Overlapped I/O under Session 0, WaitForSingleObject() always returns WAIT_TIMEOUT, and the buffer to ReadFile() never contains any valid data. This seems like a Session 0 isolation problem to me, but I can't find anything about how to work around this. Is reading from HID devices non-functional under Session 0?

谢谢.
